Browsing in Scribd, as suggested by Charmaine, I found an article on fly ash. I think it says that we should put as least as much fly ash in our papercrete as concrete. Fly ash is little spheres of glass, so it increases the insulation. It improves the properties of the concrete. It makes it more workable and allows the use of less water. It should reduce the cost of the mix. Hopefully, these advantages will carry over to papercrete.
